by Okuma
The Okuma E4809-436-060-B board is a precision memory module in the E4809 CNC Boards series from Okuma designed to serve as a volatile storage medium in OPUS 7000 CNC systems. It features dual communication channels with RS-232C or proprietary interfaces, an efficient low-power design tailored for continuous machine operation, and operates on 24 VDC power. With its primary role of storing and managing machine data, this high-density DRAM board ensures fast access to critical operational parameters and programs during machining cycles.
Built for rugged industrial environments, the E4809-436-060-B offers a range of detailed technical specifications that ensure reliable performance. It utilizes Industrial signal and power connectors for secure data and power transmission, and its compact form factor of 150 x 100 x 50 mm supports convenient panel-mount installation. The board is engineered to withstand harsh conditions, with dust and vibration resistant construction rated for operating temperatures from 0 to 55 °C. Its design accommodates rapid read/write operations via multiple onboard memory chips, each organized in high-capacity arrays for optimal data throughput.
Beyond its core functionality, the E4809-436-060-B excels in industrial automation applications due to its high packing density of memory cells and cost-effective manufacturing. Weighing just 1.5 kg, the module balances robustness with ease of handling during maintenance or upgrades. The volatile DRAM architecture requires periodic refresh cycles, but its capacitors and transistors are optimized to minimize leakage and extend retention intervals. Although data is cleared when power is removed, the module’s reliable refresh circuitry ensures system stability and rapid recovery on restart. The E4809-436-060-B enhances CNC system efficiency and uptime, making it an indispensable component for modern manufacturing automation.
